PyCharm can't run a project with MySQL database

I wanted to run my project in PyCharm IDE and got this error.

django.core.exceptions.ImproperlyConfigured: Error loading MySQLdb module: dlopen(/Users/boris/env/lib/python2.7/site-packages/, 2): Library not loaded: libmysqlclient.18.dylib
  Referenced from: /Users/boris/env/lib/python2.7/site-packages/
  Reason: image not found

After googling a while I figured out there is a mess with DYLD_LIBRARY_PATH environment variable. So, first I needed to locate the path where libmysqlclient.18.dylib located.

$ locate libmysqlclient.18.dylib

Done. In Run/Debug Configurations in Environment variables I added (plus to PYTHONUNBUFFERED=1) DYLD_LIBRARY_PATH=/usr/local/mysql-5.5.22-osx10.6-x86_64/lib/:$DYLD_LIBRARY_PATH.

It started working.
